IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. 126,013, dated April23,1822. 4

SPEcmroATloN.

To all lwhom it may concern:

Be it known that I, HORACE Gr. BROWN, of Collinsville, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Irenches; and I do hereby declare that the following isa full, clear, and exact description thereof, whereby a person skilledin the art can make and use the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My invention consists in a new method of securing the rest against whichthe adjusting screw of a monkey-wrenchy abuts to the bar which forms thefixed part of the wrench, and to the end of which the handle is usuallyattached. The object of my improvement is to obtain a more rigid andstrong connection between the parts, so as to prevent all yielding orspring when the tool is in use.

In the accompanying drawing, Figure 1 represents the side of a wrenchhaving my improvement, with the wood part of the handle removed to showthe interior construction. Fig. 2 is a top view of the same.

A is the bar of the wrench, with the fixed head or jaw B at one end, andwhich is tapered at the other to receive the handle. C is the movablejaw, sliding on the bar A in the usual manner. It is furnished with anut lfor receiving the screw D, which moves it back and forth, asdesired. E is a milled head for turning the screw D; this head isusually let a short distance into the bar A, forming a shoulder, whichprevents the screw from being moved forward. l F is the rest againstwhich the screw D abuts, and which receives the whole pressure from thejaw when the tool is in use. Gis the ferrule 0f the handle. The rest Fis inserted into the bar A by making a recess in the latter forreceiving the elongated base of the rest, as shown in the drawing. Thebase of the rest is carried rearward under the handle, and fits into thebar A with a dovetailed or square joint, so that the part which extendsinto the handle forms part of the tang of the handle. This piece F isrmly bound to the bar A by the ferrule G, which is irmly driven on withthe handle, or vset in its place before the wooden part is attached. Thehandle is fastened on by means of a small nut, 0r riveted in any usualmanner.

By means of my improvement the strain, when the tool is in use, isbrought directly from the end of the screw D to the bar A, and nottransmitted to the handle, as is usually the case. The rest F issometimes welded directly onto the bar A; but my improvement makes astronger fastening, owing to the difficulty of getting a perfect weld,and at the same time a cheaper and better one.

Claims.

held together by the ferrule G, substantially as described.

2. The combination and arrangement of the separate parts F, G, and A,substantially asherein described.
